BooK-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent 110.345.506, dated July is, lese.

Application filed Apr-i123, 1884.

Warren, in the county of Warren and State of V Pennsylvania, and at Stanton, in the county of Stanton and State of Nebraska, have invented a new and useful Book-Folding Machine, of which the following is a specification.

Said bookfolding machine, although complete in itself as a folding-machine, is used in connection with a book-pasting machine of our invention, which is also complete in itself; but the functions of these two (2) machines are intimately connected in the process of manufacturing books or pamphlets, said process being also new and constituting one of the three (3) elements of our entire invention and the above two (2) machines the other two (2) elements. Y

The object of our entire invention is to cheapen the manufacture of small books; Thekind of books especially intended are small pamphlets with exible coverswsuch as almanacs, advertising-circulars, Ste.

The method or process of manufacturing is completely setfforth in a separate application.

There are four plates of drawings with five figures illustrating our improved book-fold ing machine.

Figure 1 is a side elevation; Fig. 2, alongitudinal sectional elevation from the side opposite that shown in Fig. 1, the cross-heads 20 and 21 being removed; Fig. 3, a plan of the machine with the top removed, and partly in section; Fig. 4, the plan of the table, and

Fig. 5 an end elevation, partly in section.

The sections are not intended as continuous sections through certain parts of the entire machine at certain locations, but parts are shown insection or shown removed in the dif! same parts in all of the figures.

The letters a a designate the side-frame castings of the machine, and the letters b b the cross frame pieces. Where no particular methods, or none at all, are shown for fastening one part to another, ordinary methods of fastening similar parts together are presumed.

Serial No. 128,907. (No model.)

An operator sits on each side of the table of the folding-machine and places one of the flattened-out books, back downward, upon the guide-plate 14 at the time the cross-head 20 is elevated. When the crosshead descends, the vertical blade 2, which is carried by the .latter, strikes the book along the fold-line and presses it down upon a vertical blade, 1, which is held in a position -such that its top edge is just below the book-back. The lower edge of the upper blade, 2, is chamfered to correspond to a groove along the upper side of blade 1, and the two (2) b lades come close enough together for the upper blade to press the book at the fold-line into the said. groove of the lower blade, 1, and to clamp or pinch the book. 'The motions of the two (2) blades thereafter are coincident and downward. They consequently draw the book downward between the guides, (shown on the guide-plates 14,) andsuiiciently far that the fold-line of the book may be in a horizontal line passing between the rollers 3. The blades 1 and 2 then release their hold upon the book and separate, blade 2 ascending, leaving the book folded loosely betweenk the guides 14. As soon as blade 2 has risen sufficiently a spring, 33, pushes the book endwise until it is grasped between the rollers 3, which rotate toward each other in a direction outward from the center of the table. One of the rollers is pressed against the other by means of a spring,

(shown at 47 in Fig. 1.) Consequently the book in passing between the said rollers is pressed along the line of the fold. The books are delivered from the rollers into trays 44, attached in a suitable manner to the sides of the machine. One only is shown in the drawings. The books are shoved along in the trays automatically by means of the blocks 43. There are three (3) principal shafts running crosswise of the machine-wiz., 36, 37, and 3S. Upon shaft 36 are the belt-pulleys 12, for the driving-belt; also a pinion, 11, which engages with a spur-wheel, l0, on shaft 37. The said spur-wheel in turn engages with a smaller spur-wheel, 9, upon shaft 38.' The cross-head 20 is fastened to the upper end of a'vertical shaft, 23, which slides up and down through guide-bearings in the table-top c c, and in the cross-frame plate 35, and is guided bythe cross-head 21 sliding upon the posts 22. Said shaft 23 is operated by means of a disk-cam, 24, upon the shaft 37. A groove, 25, is made in one face of the disk, and a roller, 26, turning about a pin projecting from the lower end of shaft 23, is made to roll along the groove as the disk rotates. One part of said groove 25 follows the arc of a circle, while the remaining portion follows a chord of that circle. As the disk moves in the direction of the arrow in Fig. 2, the roller 26 and consequently the shaft 23, are elevated from the position in Fig. 2 to the position shown in Figs. 1 and 5. Vhile the roller is following the circular portion of the groove the cross-head remains elevated. After the roller reaches the end of the circular partit descends along the chord until it reaches its lowest position, as seen again in Fig. 2. The crosshead 20 is one contin nous piece divided and spread out at the middle, and having a downward-projeeting arm on each side, which carries one ofthe folding-blades 2. Another cross-head, 21, is placed through the opening of cross-head 20, and is also secured to shaft 23 and at right angles to cross-head 20. Cross-head 21 has eyes at its ends fitted to slide upon vertical guideposts 22. Said guide-posts are fastened to the top plate or table,c. They serve to guide the cross-heads, so that the folding-blades 2 2 always move in the saine vertical planes, and in line. The blades 2 are thin metal plates of the shape shown, and are secured tothe crosshead 20 by means of binding-blocks and screws, as seen in Figs. 1 and 5. rllhe springs 33, which serve to push the books between the rollers 3, are fastened to the insides of the side-frame castings, a. Said springs are connected by means of strings 19 to adjusting-screws 18,

carried by crosshead 21. Said screws pass through a short piece fastened crosswise to the under side of erosshead 21, have eyes at their ends, to which the spring-strings are attached, and nuts above the piece for adjusting the lengths of the strings. rlhe strings 19 pass through holes in the table, and over little pulleys held in a pulley-frame which is fastened to the under side of the table. After the spring has pushed a book between the rollers 3, and before blade 1 is allowed to rise, eross-head 21 draws the strings 19 taut, and pulls the spring back and holds it out of the waynntil blade 1 rises to'its elevated position. \Vhen the erosshead descends, the spring is relieved, and, coming in contact with the side edge of blade 1, is held there until the latter is drawn down out of the way again, when it pushes the succeeding book into the rollers. Blade 1 is guided in a slot in a block, 27, which is secured to the inside of the sideframe easting,a. Said block 27 has a vertical hole through its center,through which a short stem, 2S, can freely slide. The lower edge of blade 1 is secured in a slot in the top of stein 28. The lower end of stem 28 carries a boss, 29, into which the hooked rod 30 is secured e, by means of a sctscrew. Said rod also passes through and is guided by frame plate 34. The hook on its lower end engages with a campieee, 31, secured to the side of the spur-wheel 10. rllhe corresponding cam-piece for operating the corresponding hook on the opposite side of the machine is carried by a sector, 32, having a boss fastened onto shaft 37. A spring, 45, fastened to one end of the side-frame casting, and having a slot at the free end through which cam-rod 30 passes, presses against the under side of boss 29, and when the hook on cam-rod 30 is disengaged from the cam 31 said spring keeps the blade 1 in its elevated position just beneath the top surface of the table by holding the boss 29 against the bottoni of guide-block 27. Blade 2, in descending, then presses the book at the fold-line down upon and into the shallow groove in the top edge of blade 1, and in further descending pushes the book and blade l, and the parts 2S, 29, and 30, attached to the latter, along before it until blade 2 reaches the end of its stroke, the spring 45 in the meantime holding the book firmly against the lower edge of the operating-blade 2. Ey this means the book is creased along the fold-line, and is left loosely folded between the parallel downward projecting guides on the guide-plates 14, and when relieved by the separation of the blades 1. and 2 the book is in a position to be pushed endwise by the spring 33 between the rollers 3, which give the book the final pressing and deliver it into the tray 44 at the side of the machine. A slot is made in cach side of the table along its cross-center line, and of a width to accommodate the guide-plates 14. One of said plates is inserted into the top of the table on each side of the slot, and with its guiding end projecting down into the slot. Said plates are secured to the table by means of screws, and can be adjusted endwise to leave any desired width of opening between the plates. It is necessary that the flattened book should be placed squarely upon the guide-plates, and so that the fold-line will be in the plane ofthe folding-blades 1 and 2. In order to enable the operator to readily and certainly so place the books, a device is att-ached to the guideplate on the left of the operator, which serves that purpose. It consists of a plate, 1G, having a vertical branch, and provided with two (2) milled-headed screws, 17, each of which carries a block, 15, whose lower side coincides with the top surface of the left guide-plate, 14. Plate 16 is secured to the top of the table by means of a screw, and can be adjusted by rotation about the said screw, so that its end may come parallel with the edge of a book to be folded. The screws 17 can be moved independently, and when a book, 48, is placed against the blocks 15 by turning one or the other screw the book may be brought into proper adjustment for folding. The machine works continuously, and the operator has ample time to place a book while the foldingblade 2 remains elevated.

adjustedv to be folded. The pressing-rollers 3 are fastened to the upper ends of parallel vertical spindles 4, which are supported by the spindle-bearing blocks 13. The bases of the latter are parallel plates, which t against plane surfaces of slightly-projecting portions Each said bearing-block is attached to the frame-casting a by means of two (2) bolts, as seen in Fig 1, and can be adj usted in position, the bolt-holes being oblong, as seen at 8O in Fig. 2. The one on theright in Fig. 1 is adjusted loosely enoughv to be under the control of the spring 47, shown placed on the side of the machine. Said spring is coiled around a short pin, which works loosely in a hole in a split block, 49, and has a nut at its outer end for regulating the tension on the spring. A rod, 50, secured in the end of said pin, presses with its opposite end against the edge of the bearing-block. Other forms of springs might be used, which might be attached to the side-frame casting near the bearing-block. One of the roller-spindles has a small miter-wheel on its lower end,which engages with another miter on the end of crossshaft 3S. Said shaft is carried in bearings supported by the side-frame plates, 34, as best seen in Fig. 5.l The roller-spindle to which the miter is attached carries a spur-wheel just above the miter, which engages with and drives a similar wheel upon the lower end of the other The side-frame plates, 34, and the cross-frame plate 35 are secured to the under sides of the pendent branches of the middle portions of the side-frame castings by the same bolts.- Theslotted side piece, 42, is fastened against the ends of the above frame-castings. A stud, 41, is secured in the slot of side piece, 42, which serves as a support for avibrating arm, 40, and about which arm 40 oscillates. The lower end of Varm 40 is slotted, and a pin in a small disk-crank, 39, slides in said slot and gives the arm an oscillating motion about stud 41. Atray, 44, is attached to the side of the framing a, and the books are propelled by the rollers 3 through a slot, 81, Fig. 3, into the tray. The upper end of the arm passes through a slot in the bottom of tray 44, and through a slot in the block 43. Consequently the block 43 is made to reciprocate in the tray, whereby it propels the books along toward the opposite end of the A tin shield is placed over the vibrating arm 40 and its connections to prevent the opcrators clothing from catching onto them.

We claim as new and desire to secure by Letters Patenta 1. The combination of the book-adjusting device, consisting of the plate-frame 16, the adjusting-screws 17, and the blocks 15, with the two (2) guide-plates 14, having foldingguides at their adjacent ends, between which a'boolr is to be drawn and guided and held in the process of folding.
